Help with case when

I need help.
This is the code I currently have and need to change:
p.code as "Code",
p.detail_type as "Detail Type",

p.code shows diagnostic code numbers and billing procedure numbers
while p.detail_type indicate which is which. Diagnostic code numbers
are designated as '-2' (minus 2) in the 'detail_type' and procedure
codes are designated as '-4' (minus 4) in the 'detail_type.' The query
I am using now (see below) gives me duplicate appt dates to show both
the diagnostic code and procedure code. I need to clean this up a bit.

What I want this to do is find a statement that will separate the codes
into diagnosis numbers and procedure numbers and place these numbers in
different columns in the ad hoc report that is generated.

I would like something to the effect of:
If p.detail_type = -2 then place the code number in a column known as
"Code"
If p.detail_type - -4 then place the code number in a column known as
"Procedure"

Any ideas on how to write this?

Select
/* Individual Client Task List */

a.Provider as "Provider",
a.Apptdate as "Session Date",
a.Appttype as "Session Type",
p.code as "Code",
p.detail_type as "Detail Type",
a.Complaint1 as "Note Written",
a.Signoffinits as "Co-Signed",
a.Lastname as "Lastname",
a.Firstname as "Firstname"

CASE p.detail_type WHEN -2 THEN p.code END AS Code,
CASE p.detail_type WHEN -4 THEN p.code END AS Procedure,

to get 2 entries for each actual appointment (as shown below).

Is there a way to force these to combine into only one entry like this?

Stop writing code like this. You never cram two or more attributes
into one column. Hey, why not have a column for "squids and
automobiles", too?

What you have done is re-invent the variant record from COBOL, FORTRAN,
Pascal, etc. and other procedural languages.|||That's a great idea!

I think I remember seeing a squid looking automobile thingy in some animated
film recently.

Joe, Did you create the database used by the film company?
